Scientists Conclude Blue Light Is Harmless After Global 15-Year Experiment Involving 8 Billion Subjects
After concluding the most extensive longitudinal study in human history, a project informally titled “The Entire Population of Earth Staring at Their Phones Before Bed Every Single Night Since 2010”, researchers have officially exonerated blue light as a disruptor of sleep.
“We finally have the data set we needed,” said lead sleep researcher Dr. Mel Atonin. “We observed billions of subjects holding glowing rectangles two inches from their retinas until the precise moment of unconsciousness. The results were conclusive: the hue of the light is irrelevant. We are sleeping poorly, but it is not because of the color spectrum.”
The study suggests that previous concerns about “screen time” failed to account for the confounding variable of “what is actually on the screen.”
“It turns out, the wavelength isn’t what keeps you awake, it’s the content of the light,” Dr. Atonin explained. “We found that reading an email from your boss with the subject line ‘Quick chat?’ induces the exact same level of panic and insomnia in ‘Night Shift’ amber mode as it does in full, retina-searing high definition.”
The report notes that the human brain is remarkably resilient against photons, but highly susceptible to information.
“We tried to trick the brain by making the screen warmer, softer, more candle-like,” Dr. Atonin continued. “But the brain knows that the soft, orange glow is still delivering a news alert about the economy collapsing or a video of a stranger yelling in a grocery store. The optic nerve is relaxed, but the amygdala is screaming.”
Dr. Atonin concluded the press conference by noting that while they have solved the blue light mystery, the team is already pivoting to a new study. They plan to investigate if “doomscrolling” counts as cardiovascular exercise if your heart rate remains elevated for six hours straight.
“We are pretty sure the answer is no,” said Dr. Atonin, rubbing his eyes. “But I’ll probably stay up until 3 a.m. reading about it just to be sure.”
